This is a randomized, double-blind, placebo-controlled study to document the long-term effect of treatment with mometasone furoate nasal spray in moderate to severe adenoids hypertrophy as reflected by the need for removal of the adenoids within one year of the treatment regimen. Subjects will be assigned treated with either mometasone furoate nasal spray or placebo for 3 months. Subjects will be followed for an addition 12 months. Serious AEs will be followed starting first dose-till 30 days after study treatment period completion.
